Anyone know what the "Gameplay balancing" in the 1.6 update was?

It's a single-player action-puzzle game which already feels pretty darn balanced to me and I'm worrying that I might have to make backups of my older installers to make sure that I don't get an experience that's been nerfed for all these whippersnappers too young to have ever owned a SNES.

I'm familiar with these changes (they were introduced in version 1.5, but GOG finally got version 1.6 after months with outdated 1.4):
* Swedish localization
* Fishbunjin nerfed
* Higher droprate for fishbuns
* Fix for particle effects

Ahh. That'd make sense. I did find Fishbunjin's difficulty annoyingly divergent from the rest of the game.
